Yuan Liu 6d0f0ebd8a hv: implement ivshmem device creation and destruction
For ivshmem vdev creation, the vdev vBDF, vBARs, shared memory region
name and size are set by device model. The shared memory name and size
must be same as the corresponding device configuration which is configured
by offline tool.

v3: add a comment to the vbar_base member of the acrn_vm_pci_dev_config
    structure that vbar_base is power-on default value
